Abstract:

Purpose

Testing tumor samples for the presence of a mutation in the epithelial growth factor receptor (EGFR) gene is recommended for advanced non-squamous non-small cell lung cancer (NSCLC) patients. We aimed to collect data about common practice among Medical Oncologists treating lung cancer patients, regarding EGFR mutation testing in advanced NSCLC patients.

Methods

An internet-based survey was conducted among members of the Israeli Society for Clinical Oncology and Radiotherapy involved in the treatment of lung cancer patients.

Results

24 Oncologists participated in the survey. The participants encompass the Oncologists treating most of the lung cancer patients in Israel. 79 % of them use EGFR testing routinely for all advanced NSCLC patients. Opinions were split regarding the preferable biopsy site for EGFR testing material. 60 % of participants recommend waiting for EGFR test results prior to initiation of first-line therapy.

Conclusions

EGFR testing is requested in Israel routinely by most treating Oncologists for all advanced NSCLC patients, regardless of histology. In most cases, systemic treatment is deferred until the results of this test are received.
